Research on data architecture of multispecialty geological spatial information in big data environment

Le résumé fourni par la source

Big data has brought new technology, new model and new impetus to the development and reform of geological survey. Data is a valuable resource for an organization, and data architecture is an important decision for data management. This paper puts forward the requirements of geological information data architecture, analyzes the definition and classification of the architecture, expounds the core of the data architecture: data model and data flow direction, proposed the design principles of geological spatial data architecture and the management process of data aggregation, storage, management and service, and proposed a three-layer and three-support data management framework based on the upload file model and core data model of geological information, which supported the development of geological spatial data management system. The unified management and centralized service of multi-specialty geological spatial data have been realized.
